Over 1,000,000 page views per month. Jmol/JSmol is a molecular viewer for 3D chemical structures that runs in four independent modes: an HTML5-only web application utilizing jQuery, a Java applet, a stand-alone Java program (Jmol.jar), and a "headless" server-side component (JmolData.jar). Jmol can read many file types, including PDB, CIF, SDF, MOL, PyMOL PSE files, and Spartan files, as well as output from Gaussian, GAMESS, MOPAC, VASP, CRYSTAL, CASTEP, QuantumEspresso, VMD, and many other quantum chemistry programs. Files can be transferred directly from several databases, including RCSB, EDS, NCI, PubChem, and MaterialsProject. Multiple files can be loaded and compared. A rich scripting language and a well-developed web API allow easy customization of the user interface. Features include interactive animation and linear morphing. Jmol interfaces well with JSpecView for spectroscopy, JSME for 2D->3D conversion, POV-Ray for images, and CAD programs for 3D printing (VRML export).

The EdytorNC project now consists of four applications that can be useful for programming and operating CNC machine tools. EditorNC is a specialised text editor for CNC programmers. FTPserver is a simple FTP server for transferring cnc programs to and from the machine. SerialPortFileServer is a simple server for transferring cnc programmes to and from the machine via RS232 ports. ProgramManager is a program that makes it easy to search for cnc programs based on, for example, part number, part name contained in the first three comments in the cnc program. Some EdytorNC features : bolt holes calculation; solutions of triangles calculation; speed, feed calculation; conversion inch/mm, mm/inch; code colouring; RS232 data transmission with automatic file saving and possibility to download new CNC program directly from machine (beta function, look in tool tips in serial port configuration dialog). Clipboard to keep texts from system clipboard.
